strength, the alloy having a tensile strength 1 equal to that of mild steel and, unlike other bronzes, capable of being forged, rolled, welded, soldered, drawn or otherwise worked in a manner similar to iron or steel. This alloy may be produced in different forms,

suchas ingots, pigs, billets, bars, etc., for
